Who Is Calling Which Page on the Web?

Web identity and resolution identifies, authenticates, and locates users on the Web. It´s a critical aspect of Web Real-Time Communications (WebRTC), a joint W3C and IETF effort to develop standards for secure real-time communication over the Web. Although WebRTC proposes a security architecture to integrate with federated Web identity systems, the architecture isn´t compatible with identity protocols that don´t satisfy WebRTC requirements. To fill the gap, the authors describe two alternative architectures to adapt incompatible identity protocols to the WebRTC security architecture. They also describe a Web-of-trust model to address hierarchical identity systems´ limitations, and a mirror-presence system to locate users on the Web in real time while they are moving between websites.
